You won't find Irish organic sugar for it, alas (although you could substitute organic Irish honey in the tart itself ) but Billington's is widely available, and I find it different from ‘ordinary' sugar. Organic Irish apples are in season and, together with the cream and eggs, should be easy to source, along with organic ice cream to serve with the tart — not sure about the whiskey!

Serves 4

You will need

250g/9oz shortcrust pastry

50g/2oz ground almonds

4 large cooking apples, eg organic Bramley

Seedling, peeled and diced

30m/2tbsp sugar, or as required

250ml/9fl oz cream

3 egg yolks

50g/2oz caster sugar

Dash of whiskey

Method

Preheat a fairly hot oven, gas mark 6, 200°C (400°F).

Line four individual tart tins with the pastry.

Sprinkle some ground almonds on the base of each one, then add the apple and enough sugar to sweeten.

Heat the cream. Beat the egg yolks and sugar together, then stir in the cream and a dash of whiskey.

Spoon a little of the cream mixture into each tart, reserving the rest to serve as a sauce.

Bake the tarts in the preheated oven for 25- 35 minutes, until the pastry is golden brown and filling is cooked.

Meanwhile, pour the remaining egg yolk and cream mixture into a bowl. Place over simmering water and cook, stirring constantly, until the custard thickens.

Set aside, and keep warm.

Serve the tart, dusted with icing sugar, with the warm custard, accompanied by organic vanilla ice-cream, thin almond biscuits and seasonal berries if you wish.
